I'd love to see the manufacturers all agree to publish their reliability stats.
With other products, we can see the returns-in-warranty data, and therefore base decisions on hard facts. For example, I have published on here our warranty returns data on controls and a couple of other products.
I agree, however that would still only be a fraction of the story. It would not take in to account out of warranty repairs or repairs undertaken independently that may not be reported to the manufacturer and how could the manufacturer effectively determin whether a part failure was manufacturing, material issue or poor install without every faulty part being sent back.
